Multi-platform wind turbine tower

Abstract

The purpose of the invention is to provide a multi-platform tower that allows production costs to be significantly reduced, since the tower is suitable for different types of turbines. For this purpose, the improvements consist in obtaining a profile which is based on frustoconical sections having various inclinations and which corresponds geometrically with a load envelope obtained from the superimposition of theoretical profiles of respective towers designed specifically for a plurality of different turbines. Given that the lower part of the turbine comprises securing means having a different diameter, it is necessary to include a series of adaptors or reels ( 4 - 4 ′) having a frustoconical configuration and which allow the tower to be adapted to any type of turbine. If necessary, a second adaptor ( 11 ), formed consisting of ring in the form of a wedge, could be included, the adaptor modifying the angle of the plane in which the blades rotate, thereby distancing the free end of the blades from the tower.

The invention claimed is: 
     
       1. Multi-platform wind tower comprising a series of two or more joined vertical concrete segments, and wherein the concrete segments forming the tower have a frustoconical configuration, where each of the concrete segments has a different inclination, such that a broken profile is obtained corresponding to a profile for the tower, characterized in that the broken profile of the tower geometrically corresponds to a load envelope obtained by superposing the concrete segments corresponding to the profile of the towers designed for a turbine, and where the turbine is secured to a top end or coronation ( 1 ) of the tower by an adaptor or reel ( 4 ,  4 ′) having a metal body with a profile having a lower base with a diameter matching a diameter of the top end or coronation ( 1 ) of the tower and an upper base having a diameter of the turbine to be installed, and where said adaptor includes means for securing the lower base to the top end or coronation of said tower and for securing the upper base to the turbine. 
     
     
       2. Multi-platform wind tower, according to  claim 1 , characterized in that the adapter or reels ( 4 , 4 ′) include a corresponding lower ( 5 ) flange at the lower base of said adapter or reels and an upper ( 8 ) flange at the upper base of said adapter or reel, and where said adapter or reels include orifices ( 6 - 9 ) for the passage of corresponding bolts securing the adapter or reel to the tower coronation and a turbine articulation means. 
     
     
       3. Multi-platform wind tower, according to  claim 1 , characterized in that when the separation between a free end of turbine blade tips and the tower is not suitable, a second adaptor ( 11 ) having a circular crown with a variable thickness and defining a wedge having a plurality of evenly distributed orifices ( 12 ) is provided between an articulation means ( 13 ) of the turbine and the turbine, by means of corresponding bolts ( 14 ).
